Abstract

Novel halogenated trifluoromethylbenzenes have the structural formula ##STR1## wherein X is halogen, preferably Cl, F or Br, and R is a group selected from the group consisting of --COOH, --C(O)NH 2 and --CN. These compounds are intermediates for pesticidal trifluoromethyl diphenyl ethers and are converted thereto by replacing the fluorine para to the trifluoromethyl with substituted phenoxy group in aromatic nucleophilic substitution. A novel intermediate which is converted by reaction with cuprous cyanide and HONO to compound having the above structural formula where X is F and R is --CN is 2,3-difluoro-5-(trifluoromethyl)aniline and has the formula ##STR2##
